Strombosia glaucescens Engl.
Strombosiopsis rigida Engl.
Strombosia pustulata is an evergreen tree usually growing up to 20 metres tall, but with some specimens to 45 metres[
]. The crown is small and dense; the bole straight, 20 - 100cm in diameter with short sharp root spurs[
The tree is harvested from the wild for its timber, which is traded internationally. The seeds yield an oil that is used for making soap.
West tropical Africa - Sierra Leone to Gabon.
Firm-ground rain-forest on well-drained soil; moist forest; closed shady forest, often on lake- and river sides; at elevations from near sea level to 770 metres[
|Other Uses Rating||
An oil from the seeds is used for ointment and making soap[
The heartwood is pink or pale brown with purplish streaks; the sapwood wide, yellowish and sharply defined. The texture is fine; the grain fairly straight; lustrous but with an unpleasant smell when freshly cut; rather oily to touch[
]. The heartwood is highly durable and is immune to termite and other insect attack[
]. The timber saws cleanly but is apt to spring and split; it works well and takes a smooth finish; glues well; splits in nailing and requires preboring; can be sliced into veneers[
]. Often used in the round as building poles and transmission poles (treated), striking tool handles, turnery, heavy-duty flooring[
]. It has been suggested as a substitute for European boxwood[
